Just comment out the jmp to normal section, should be more easier.

Do we need a new variable FALLBACK_ONLY ?

I put together the attached patch to try to modify it nicely, but I'm
not
sure it works as I intended.  I wanted to only try to jump to normal
when
there is a normal, but the variables are all FALLBACK-oriented.

[LinuxBIOS] Tyan s2892 the OLPC way

[yhlu]

can we make one more generic buildrom and put into tree?

git or svn should be ok.

it should only produce payload only.

How abut call it buildpayload?

We can use Myles Watson's modification as a base.

there is  a buildrom tree at openbios.org

use the co command for linuxbios but specify buildrom.

actually, the OLPC buildrom is generic enough at this point that we should
be abe to use it with few mods. I extended it a bit and all we need is a set
of pre-built .config files, one per mainboard, and a setting in the file. It
is very close.

In fact I just used  buildrom to build a linux-in-flash for the sun ultra40
workstation!

ash prompt in < 10 secs. most of that time is the fixed delays in the kernel
...

thanks

but the one still include VSA and linuxbios in it.

busybox
kernel
kexec-boot-loader
kexec-tools
mkelfimage
uclibc

do i need kexec-boot-loader?

yes

If you look in deploy, for now, you can use the payload, which is built
without containing linuxbios or vsa. That is how I got a working payload for
ultra40.

What we need to do with buildrom is extend it so we can have a config file
for a given platform, that builds the proper kernel AND linuxbios, and has
payloads like VSA as an OPTION. I think this is easy. I did it (sort of) for
qemu.
